CAN-ENDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 726,799, dated April 28, 1903.

Application filed June 7,1902. Serial No. 110,697. No model.) I

To all whom it may concern.-

Be it known that I, LOUIS LAMBIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Can-Ending Machines, of which the following is a specification.

This invention relates to machines for pressing the formed ends of a can onto the body thereof preparatory for soldering. Its object is to provide a simple machine for the purpose indicated that will be eificient in oper: ation' and of an exceedingly large capacity; and it consists in the various features of construction and details that will be described hereinafter. v

In the drawings, Figure 1 is a side elevation of a machine embodying this invention. Fig. 2 is a front elevation of the same, showing one section after the ends are pressed on and with parts omitted to prevent confusion. Fig. 3 is an enlarged view of a portion of the disk on the left of Fig. 2, showing the slidable sections. Fig. 4 is a section on line 4. 4 of Fig. 3. Fig. 5 is a-detail of one of the grippers. Fig. 6 is a detail of one of the saddles. Fig. 7 is a sectional view showing the can parts ready to be pressed together. Fig. 8 is a similar view after the disk-section has been forced in and the ends pressed on. Fig. 9 is a detail showing means for ending cans where the head is provided with a tang for opening. Fig. 10 is a sectional plan view of the same, taken on the line 1O 10 of Fig. 9. Fig. 11 is a detail showing the recesses c". Fig. 12 is a sectional view taken through a portion of one of the disks, showing the recess 12 and the gripper g therein and the saddle e.

A represents a frame of suitable material and outline with a base a and sides 0., in which are bearings 0. for a revoluble shaft B. This shaft may be driven in any desired manner, as by a belt around'the" pulley 1). Bigfdly mounted on this shaft is a disk 0, which for convenience will be called the righthand disk, and an enlarged hexagonal hub c, which carries the left-hand sectional disk 0, composed of the sections 0'. Ways 0 are cut in the hub c for the bases 0 of the sections 0. The object of sliding these sections is to press the ends upon the body after they have been clamped in proper relative positions, and the movement is accomplished by arms 0 secured to the bases 0 by bolts 0 in slotted holes 0. These arms are adjusted by nuts 0 on studs 0 secured to the sections 0 and passing through lugs 0 on the arms 0 At the ends of the arms 0 are cam-rollers o which are adapted to engage with camplates 01 d on a stationary cam-drum D, socured to the frame A.

The can-bodies e are fed to the machine through a chute E (shown in Fig. 1) and are caught by saddles e, which are rigidly secured to the inner faces of the disks 0 O and form a part of the can-gripping mechanism. Immediately forward of the chute for the bodies are a pair of chutes F for the ends f. These are also caught in the saddles e, which are grooved at 2 next to the disks, to receive the ends and hold them in proper position for engagement with the body. After the bodies and ends have been caught by the saddles they are next engaged by grippers g, which are. grooved to receive the ends and coact with the saddles to securely hold the bodies and ends in proper position for ending. These grippers are semicircular in outline and normally rest in similar-shaped recesses 0 out in the disks 0 and 0. They are provided with elongated bearings'g, which slide and turn upon short rods h, which are supported at one end by lugs e on the saddles e and at the opposite end by brackets h on the disks. Springs h on the rods h tend to hold the grippers in their normal position. To cause the grippers to engage the can parts, they must first be pressed in against the action of the springs until. free of the disks and then turned der to hold the gripper in positive engagement with the cans, spring-pressed catchesj are arranged on the disks to lock the pins g The operation of ending the can may now be readily understood. The disks being rotated, as shown by the arrow in Fig. 1, the can-body is first caught by the saddles and lies centrally of the disks, so that there is room at either end for the ends to drop into the grooves in the saddles. The cam next forces the grippers in, and the fingers on the frame engaging the pins on the grippers swing them into engagement and the catches hold them. The body and ends being in their proper relative positions to be pressed together, the roller on the arm extending from the base of the section engages the camplate and forces the section in toward the relatively stationary disk and presses the can parts together. It is customary to form one of the can ends with a central aperture, and to allow the air to escape from the can while the ends are being pressed on there are holes 0 through the disk centrally disposed with reference to the can. As shown in this form of construction, each section is provided with means for ending two cans. The can being ended, the catchesj are released by striking the tripperj from the frame. The grippers will then swing out by their own weight and centrifugal force until they are opposite the openings in the disks, when the springs will draw them into their normal position. The grippers having released the cans, the section 0 will be drawn back by the roller 0 engaging with a cam on the cam-drum D and allows the cans to be discharged into any convenient chute, such as K. (Shown in Fig. 1.)

In frequent instances it is desired to form cans with tangs for opening them after they are sealed. For this purpose I have provided the device shown in Figs. 9 and 10. The chute F is provided with a slot f to register with the tangs f on the ends f. When the end is discharged from the bottom of thechute, a spring-fingerf prevents the tang from turning down, and as the saddle e carries the end forward a second spring f engages the tang 5 f and turns the end in the saddle until the tang registers with a recess 6 in the saddle e. The gripper then engages the can, and the further operation is as above described.

It will be observed that by changing the shape of the saddles and grippers any form of can may be ended, and various other I changes in details of construction may readily be made, which will come within the scope of this invention, which I do not wish to limit to the exact form shown; but

What I claim, and desire to secure by Letters Patent, is-
